DIAGNOSIS: A fusiform Coluzea with strong axial ribs and no keel. Posterior whorl slope slightly concave so that the whorls are scarcely shouldered. Posterior whorl slope bearing about eight irregularly spaced fine spiral threads of varying strength. Anterior whorl slope with three or four spiral cords and numerous finer lirae.
DESCRIPTION: Shell with early whorls shouldered and bearing strong axial costae which together with the shoulder diminish in strength on the body whorl. Posterior whorl slope slightly concave on the spire whorls but becoming convex on the body whorl so that this is almost regularly convex. Posterior whorl slope of body whorl with up to eight irregularly spaced fine threads. Anterior whorl slope with three or four spiral cords and numerous finer lirae which persist on the canal. Aperture subcircular. Inner lip covered with a thin glaze. Canal short and twisted.
Height 75 mm. Width 25 mm.

It is possible that a good series of specimens would show that this species is not distinct from Coluzea angularis (Barnard). The early spire whorls are similar, the sculpture is similar and the distinguishing feature v/z. the tumid, regularly convex body whorl, seems to be variable in both species.

TYPE LOCALITY: Off Cape Point, South Africa. 250-760 fathoms. OCCURRENCE: Type locality only.
